which group is the best for the students whoare intrested in science or physics mainly

See you can either go for doing BSC in physics or something like going ahead after giving KVPY exams in physics field. But if you want to consider Engineering as your choice which has physics in it then I'll tell you about my personal experience.

Well, I was very much interested in physics in my school times. So I'll provide with the things that I considered while choosing my engineering stream and let you choose what you want.

In Physics my interesting topics include Kinematics, Properties of matter, Work Power Energy and some other ... as well as Electrostatics, Current Electricity, Electromagnetism, Optics and Modern physics. Alongside I was good and interested in coding also.

What I did not like at that point was thermodynamics and electromagnetic waves.

Now the Engineering Branches that I was interested in was Mechanical Engineering, Electrical Engineering and Electronics Engineering.

First thing to do is check the 4 years syllabus and map the syllabus according to the things that interests me at that point.

for ME, Thermodynamics was a very integral part. So I inclined a more towards EE and ECE . Electrical was having some machine designs and other systems which at that point I thought will require a lot of Electromagnetism.

ECE on the other hand was having stress on modern physics and semi conducter and have some coding based subjects also. So I opted for ECE at last. But there is very little relation between Physics as we know at 10+2 level with ECE in engineering. But I enjoyed it much and those knowledge help me out in my DIY stuffs too ...

Hope this helps .... Choose wisely...
